Dans la trace, on voit en vert qu'il y a deux imports de Droits. L'erreur pourrais venir de là, mais je sais pourquoi il y a ces deux imports.

Lorsque je commente les lignes concernant le set dans le fichier Droits.hbm.xml, il me génére l'erreur suivante : Duplicate class/entity mapping Mapping.Droits

J'ai regarder dans mes autres fichiers si je n'avais pas déclarer plusieurs fois la classe Droits, mais ce n'est pas le cas.

Je sais pas si ça aide, mais la génération automatique du code Java et DAO est correctement effectué.

Merci d'avance de votre aide.
